“We have made you into peoples [i.e., ethnicities/races] and tribes”
Cited to explain the Prophet ﷺ's decision to organize the Badr army by Muhajirun/Ansar identity.
لَّمْ تُؤْمِنُوا۟ وَلَـٰكِن قُولُوٓا۟ أَسْلَمْنَا وَلَمَّا يَدْخُلِ ٱلْإِيمَـٰنُ فِى قُلُوبِكُمْ
“[O Bedouins,] you are not yet mu'mins (believers), you are Muslims (one who has accepted Islam). Iman has not yet fully entered your hearts.”
Opens the same passage as Al-Hujurat 49:17 (already linked to this event), addressing Bedouin tribes who overstated their faith upon accepting Islam without a fight.
يَمُنُّونَ عَلَيْكَ أَنْ أَسْلَمُوا ۖ قُل لَّا تَمُنُّوا عَلَيَّ إِسْلَامَكُم ۖ بَلِ اللَّهُ يَمُنُّ عَلَيْكُمْ أَنْ هَدَاكُمْ لِلْإِيمَانِ إِن كُنتُمْ صَادِقِينَ
“They regard their acceptance of Islam as a favor to you. Tell [them, O Prophet], 'Do not regard your Islam as a favor to me. Rather, it is Allah Who has done you a favor by guiding you to the faith, if [indeed] you are faithful...'”
Revealed correcting the delegation's boast that they had accepted Islam unbidden and unfought.
